Update :
When i use the latest armbian version ("Noble Numbat") + the meson-gxbb-beelink-mini-mx.dtb and u-boot-s905 as u-boot.ext, all the peripherals worked fine (including Wifi and ethernet).
But now I'm trying to launch the installer from armbian-install command but I got an error :
The [ :meson-gxbb: ] series in the [ /etc/model_database.conf ] file is empty and does not support write to eMMC !
So is there any chance of finding a linux version that can be installed on this box? (even if it's an old version of libreelec, openwrt, debian or whatever) because with Android 5 the box is unusable and Playstore no longer works.
